bohmanwin - Bohman window

Syntax

w = bohmanwin(L)

Description

w = bohmanwin(L) returns an L-point Bohman window in column vector w. A Bohman window is the convolution of two half-duration cosine lobes. In the time domain, it is the product of a triangular window and a single cycle of a cosine with a term added to set the first derivative to zero at the boundary. Bohman windows fall off as 1/w4.

Examples

Compute a 64-point Bohman window and display the result using WVTool:

L=64;
wvtool(bohmanwin(L))

Algorithm

The equation for computing the coefficients of a Bohman window is

where and the window length is .
